People with 11 specific medical conditions can receive free NHS prescriptions, but only if they hold a valid medical exemption certificate. The certificate covers NHS costs such as prescriptions and dental treatment, though it is the certificate itself that provides the exemption, not the condition alone.
How to Apply for an Exemption Certificate
If you believe you are entitled due to a medical condition, consult your GP or doctor who will provide an application form. Once submitted, the certificate is typically issued within 10 working days. The NHS will backdate the certificate to start one month before the application date. If the certificate covers the date you collect your items, you can obtain free NHS prescriptions by marking box ‘E’ on the prescription form and signing the declaration. You may need to show the certificate as proof, but you can still collect free prescriptions without it if necessary. Certificates generally last for five years and must be renewed. Note that prescriptions are free for those aged 60 or over regardless.
Conditions That Qualify for a Medical Exemption Certificate
You are eligible if you have one of the following:
- A permanent fistula requiring continuous surgical dressing or an appliance
- A form of hypoadrenalism for which specific substitution therapy is essential
- Diabetes insipidus
- Other forms of hypopituitarism
- Diabetes mellitus, except where treatment is by diet alone
- Hypoparathyroidism
- Myasthenia gravis
- Myxoedema
- Epilepsy requiring continuous anticonvulsive therapy
- A continuing physical disability that prevents you from going out without the help of another person
- Cancer
If you are unsure about the name of your condition, seek help from your GP. Without a valid certificate, you may be liable for a penalty charge.
